Typographers test their fonts with the same sentence

A pangram is a sentence that uses every letter of the alphabet to judge the rendering and readability of a typeface on an entire page. In French, one of the most widespread reads as follows: 'Portez ce vieux whisky au juge blond qui fume'. Other systems employ different variants, such as Windows which uses the sentence 'Voix ambiguë d'un cœur qui au zéphyr préfère les jattes de kiwi'.
